ORE SEPARTNG OR- CONCENTRATNG MACHINE.

Application tiled May 113, 1907.

To all whom it' may concern:

Beit known that I, ivhxmnn lt. inns, citi- Zen of the United States, residing at `Philadelphia, in the county oi'Y Philadelphia and State of Pennsylvania, have in rented certain new and useful .imprm'ements in `(1re Sepathe ore the latter is passed through the machine.

'lhe i.u\f'cntion consists in the novel con struction andl combinations oll paris hereinafter fully descrihed and particularly; claimed.

In the drawings:#-Figure 1 is an end elevation of my improved machine.. Fig. 2 is a hmgitudinal sectional View thercoi' as on the line 2N2, ol' Fig. 1. Fig. 2% if. a transverse sectional View as on thc line Y 21, oll Fig. 2. Fig. fl. is a transverse sectional 'view as on the line. 4m4, o1: Fig. 2.

5 designates a suitahlc. tank within which is arranged a tailvering drum, l, the lower portionot which is corrugated longitndinall \v of the drum. This drum is provided with end heads (i. The end heads comprise circular flanges 7 and huhs el connected to the flanges `7 hy arms 1l; the ilangcs proi'iding means wlnrch),Y a water ievel ma) he maintained within the drum and the spaces hetwecn the arms t), providing openings tln'oughl which water, &c.,`may tiow from within the drum. Projecting from the hnhs ol.' the end heads 6 are stud shafts 11). which projectinto bearings in. Aframes or hrackets 11 extending across the tank 5 and secured to the side walls thereof. Rising, troni the brackets 11 are hearings 12 to which are litted transverselyarranged rcciprocative hars 13 on the inner ends-of which are formed gear racks 14 in engagement with gear wheels 15 secured to thc stud shafts 1l). T he outer ends ot the hars 13"carry rollers extending into grooves ol cams 16 secured to a shaft 1.7 which mounted in hearings 1S secured to one side of the tank 5, the. shaft 17 heing provided with a pulley 1l.) around which passes a helt '.211 leading from any suitahle source ot power to rotate the. shaft 17. Vihc contour ol the cams 11i is such that during the rotation ol" the shaft 17 the hars 121 will he drawn toward the shal't 17, maintained adjacent the shait a short space oi" time, and then pro- Speci'ication of Letters lPatent.

`ieeted from the shaft and projected. position a short space of time; thus reciprocating the hars 13 in a manner to cause the racks 1/1 to rock the drum 1 I'irst to one side and then to the other side,and to nring the drum to rest a short space of time at the end ol cach stroke ol1 the hars 13 for a Vpurpose hereinai'A er explained.

The upper portion o1' the smaller end of the drum 1 pr \'i.led with an. opening 2.1 having a li'aring mouth; and arranged directly ahovc the mouth oi" the opening the lower end o1" an inclined chute 22 througl'i which thel ore is led to the nntchine.

Arranged adjacent `the larger lend of he drum 1 is an endless chain conveyor 23 provided with. suitahle hut-kots 24 to carry oli' waste mal ter from the machine.. rl`he lower end ol'fthe convcycr chain 23, passes around a suitahle wheel 25 which is nxounted on a stud shaft within the tank,and the upper cnd oll the conveiycr chain passes around a similar wheel 2o mounted on a shaft 27 to which power marv he applied to actuate the HVNT.

rThe operation oi' tl ie, machineis as follows 2- The tank 5 and drum 1 are provided with water and the orc isintrmluced to the drum lhrough the chute l2 at the small end of the drum, and the orc passes to the larger end of the drum and lows out through the-opening thercinintf.) the tank 5, Irom which it is earripd h v the convevcr 251 to a suitable pointoi discharge, iuring the passage ol the ore through the drum lhc shaft 17 is rotated and through its connection with the drum 1 said drum is rocked hack and forth. During the hack and forth motion oi' the drum the corrugations inthe bottom thcreolz carry the ore from side to side., and as the drum is brought to rest at each side during the rocking there ol", the orc flows down toward the center and is then rocked to the opposite side of the drum. Thus the ore is caused to flow back and forth transversely of the drum during its longitudinal 'passage therethrough. 'lhis operation thoroughly agitates the ore and causes maintained in the the concentrates, which ar'e heavier than the waste inattcr,'to settle to the bottoni of the drum, while the `waste matter of the ore passes out through the openings in the larger end of the drinn and is carried ofi by the convcyer chain. After this operation has been carried on a sullicient length of time the enriched material is colli-voted from the hottorn oli the drum and the, gold or other ore is re- Cri covered by careful Washing or panning out in a smaller pan.

' I claim `1. y In a machineof the character described, a tank, a rocking drum mounted in said tank and having an opening discharging into said tank, said drum being conical and formed an integral struture, the bottom of said drum having corrugations therein extending the length of the drum, and throughout a portion of its circumference, brack ets car-v ried by' said tank for supporting the drum therein, a reciprocatory bar carried by one of said brackets, connections between said bar and said drum, whereby the latter is .rocked by said bar, means for reciprocating said bar, and means for feeding the ore to said drum.

In testimony whereof I ailix my signature in presence of two Witnesses.
